Am getting the below messages when I try to check for install devices with the command ibv_devices.

libibverbs: Warning: no userspace device-specific driver found for /sys/class/infiniband_verbs/uverbs1 libibverbs: Warning: no userspace device-specific driver found for /sys/class/infiniband_verbs/uverbs0

Am running ubuntu 16.4LTS in VMWare

Output of lsmod below looks OK:

Module                  Size  Used by
siw                   110592  0

I will be grateful if I can get some help on resolving this.

I had the same issue with ubuntu 16.04 and kernel version 4.8.7. I have mellanox connect x4 NIC for RDMA and I resolved it by installing libmlx5-1

sudo apt-get install -y libmlx5-1

Hope it helps.
